对外国客人当商品不能成交然后送客人出门时应该说些什么呢？

Tks! Bye bye.Hope to see you next time.

Very nice to meet you.
Looking forword to our cooperation in the future.

如果你要买东西给他,你要考虑的不是他是不是外国人,他会不会笑你,他会不会看扁你, 而是你如何把你的商品买的更多.你是销售,不是外交家.

所以, 如果他没有被说服卖什么东西, 你应该继续利用他还在店里的每一秒钟向他推销你的产品.比如:

Hey, sir/madam, we can talk about it if you are really interesting.

How about I give you more discounts?

It is a unique goods. You will never find that anywhere else.

下次再来，对不起
